Application filed September 6, 1921. Serial No. $98,851.

To all whom it may concern Be it known that I, ALFRED Hnnnmoron, a SUbJQCt of the King of England, residing at Leicester, Leicestershire, England, have invented certain Improvements in Sole- Edge-Treating Tools, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to edge setting niachines and is illustrated as embodied in a machine of the type set forth in Unit-ed States Letters Patent No. 1,078,68d granted November 18, 1913 on application of F. B. Keall, J. Gouldbourn and A. E. Jerram in which an iron for setting the sole edge ismoved along the length of the sole edge and in which an indenting wheel is mounted near the edge setting iron so that when the edge of the sole is pressed against the iron, the upper surface of the welt or sole is pressed against the'under surface of the indenting wheel.

It is desirable that provision be made in machines of the type'above referred to for insuring that differences in thicknessofdifferent parts of a given shoe sole, as well as differences in thickness of different shoe soles, may be fully compensated for to the end that the pressure of the indenting wheel may be substantially uniform whatever the thickness of any given sole at any point. It is also important that in providing for such relative adjustment of the wheel and 'iron heightwise of the shoe, there will he 110 substantial interference with the desired continuity of the working surfaces of the tools at the upper corner of the sole edge. v

In view of these considerations, it is an'object of the present invention to provide an improved edge of setting machine of the type above referred to, by the use of which the simultaneous performance of edge setting and indenting operations may be still further facilitated by the provision of a relative heightwise movement of the edge setting iron and indenting wheel such that the wheel will follow, with substantially uniform pressure, variations in sole thickness or in the vertical contour of the upper side of the sole or welt edge.

In accordance with a feature of the present invention, this problem is solved by providing for movement of the indenting Wheel heightwise of the shoe in response to variations in sole thickness, the indenting wheel being undercut and a part of the operative surface of the edge setting iron being arranged to extend into the undercut portion of the wheel, so that heightwise movement of the wheel will not interfere with the continuity of the working surfaces of the tools at the upper corner of the sole edge.

This and other features of thein'vention, comprising various combinations and ar rangements of parts, will be understood from the following description of two embodiments of the invention, selected for pur poses of illustration and shown in Figs. 1 and 2 of the accompanying drawing respec tively. The figures are both side elevationspartly broken away, of an edge treating implement comprising an iron and indenting wheel. I The drawings illustrate a preferred embodiment of the invention in its application to'a machine having the general organization set forth in detail in United States Letters Patent No. 1,078,684, above referred to,- to which patent reference may be had-for a moredetailed disclosure of parts not herein specifically setv forth.

In Fig. 1 is illustrated an edge setting iron 10 of the type illustrated in said Letters Patent and shown more in detail in United States Letters Patent No. 1,161,868, granted November 30, 1915, on application of F. 'B. Kea'll (except for a difference in profile to adaptit for a difierent style of work). This iron 10 is adjustably fixed to a holder 12 by means of the screw 14:. The'holder 12 is mounted: in the machine and oscillated perpendicularly to the plane of the drawing in any desired way. At the uper part of the holder at 16 is'p'ivoted a bell-crank 18 against one arm of which bears a' spring-pressed plunger 20, and upon the other arm of which is rotat-ably mounted the indenting wheel 22 on the screw 24. In Fig. 1 the wheel is somewhat undercut, as at 26, and overlaps the upper bevel forming lip 28 of the iron which extends into said undercut portion of the wheel. This allows the wheel to have an adequate range of movement heightwise of the iron without materially disturbing their horizontal operative relationship or the continuity of their operating surfaces at the junction of the edge face of the sole with the upper face of the sole or welt. The entire lateral surface of the sole edge and the upper surface of'the sole or welt are thus completely finished right out to their junction.

The bell-crank and wheel have free pivotal motion about the pivot 16, the wheel being forced against .the work 29 by the spring plunger 20, the whole tool being adjusted with sufiicient play to accommodate the exsented to it.

tremes of sole thickness which will be pre- A screw limits the'movement of the wheel away from the iron.

.Fig. 2 illustrates a construction adapted for use with a double hump iron. The general problem of the double hump iron and indenting wheel. combination is discussed in UnitedStates Letters Patent No. 1,276,027, granted Aug. 20, 1918,011 the application of Ke -all, Harrington and Bassett, and need not be more specifically treated herein.

In Fig. 2 the wheel 22 is seated in a depression between the humps l0 oflthe iron and is mounted on a bell-crank l8 pivoted larly to the corresponding parts in Fig. 1.

Having described my invention, what I 1 claim as new and desireto secure by Letters Patent of the United States is 1. An-edge setting and indenting device comprising a holder, an edge settmg iron secured to the holder and having an oper-' ative surface to vtreat the lateral edge of a shoe sole,'an indentingtool for treating the upper face of the sole, and a yieldable mounting for said indenting tool to allow movement of the indenting tool heightwise of the ,work in a direction substantially perpendicular to the operative portion of its surface under pressure of said work against,

the operative surface of said indenting tool said indenting tool having 1ts operative surface extending to and meeting the operative surface of the edge iron in all positions to insure a continuous finishing surface as the indenting tool rides over a sole of uneven thickness. I

2. An edge setting and indenting device comprising a holder, an edge setting iron secured to the holderv and having an upper bevel forming lip, an indenting tool having an operative surface intersecting the surface of said lip and extending alon the upper. face of a shoe sole, and a plvotal I mounting for said indenting tool construct- All other parts are numbered si1ni-- ed and arranged to allow it to move height- Wise of the work in a direction substan-- tially parallel to the face of the edge setting iron and to maintain a close junction of said finishing surfaces so as to treat'the'upper surface of the sole all the way out to the edge.

An edge setting and wheeling device comprising a holder, an edge setting iron secured to the holder and having an operative surface for burnishing the lateral edge of a shoe sole, an indenting Wheel having an operative surface extending along the upper face of the sole edge and meeting theoperative surface of the edge iron, and a pivotal mounting for the wheel constructs ed and arranged'to allow the work tomove the wheel height'wise of the sole when the sole edgeis of uneven thickness in a direc tion substantially parallel to the face of the edge iron and to maintain the continuity of said surfaces.

4. An edge setting and wheeling device comprising an iron having an upper bevel forming lip, and an undercut indenting wheel, said lip extending intothe undercut portion of the wheel, the wheel being mounted for operative movement heightwise of the iron to follow a vertically uneven sole edge and eo-operating with s'aidlip to form a substantially continuous sole edge finish ing surface.

5. An edge setting and indenting device comprising a holder, an edge setting iron secured to "the holder'and having an operative surface arranged to treat the vertical edge of a shoe sole, and an indenting too-l also secured to the holder'and arranged to treat the upper sole or welt face, said, edge
